EYELETING -MACHINE.

SPECIFICATION forming part of Letters Patent N0. 691,012, dated January14, 1902.

Application filed April 8, 1901.

To all whom it may concern.-

Be it known that I, EDWARD L. SIBLEY, a

nington, in the county of Bennington and State of Vermont, have inventeda certain new and useful Improvement in Eyelet-Presses, of which thefollowing is a full, clear, and exact description.

This invention relates more particularly to a press designed for use insetting eyelets or rivets of the class represented in my Patent No.358,225, granted February 22, 1887, and known on the market as Challengeeyelets; and the object of the invention is to provide a positivemovement in both directions for the sliding plate containing an incline,by means of which the punch is held in place to drive the eyelet throughthe paper or other material and is allowed to drop into the bed of themachine when the eyelet or rivet is to be upset.

The invention consists of a sliding-plate incline normally held by meansof a spring beneath the punch and positively moved in both directions bymeans of a trip-lever,which is actuated by the punch-lever, all as Iwill proceed now more particularly to set forth and finally claim.

In the accompanying drawings, illustrating my invention, in the severalfigures of which like parts are similarly designated, Figure 1 is a sideelevation with the bed of the machine partly broken out and the partsshown. in the position for punching. Fig. 2 is a vertical section withthe parts shown in position for upsetting the rivet or eyelet and thenear side of the punch-lever broken away to show the rear slottedportion of the cam. Fig. 3 is a top plan view of the sliding-plateincline detached. 1

The bed a, overhanging neck I), and head 0 may be of usual construction.In an anvil (Z on the bed is arranged the punch e, having within asuitable opening therefor in the bot tom of the anvil. Beneath thispunch is ar ranged the sliding-plate incline f, supported upon lugs gand having the ilat surface 7t, against which the head of the punchrests in the act of inserting the eyelet in the material, and having theincline 2', down which the punch drops when it is desired to upset theSerial No. 54,911. (No modeLl eyelet or rivet, as respectively shown inFigs. 1 and 2. This sliding plate is normally pulled to the rear by aspring j, so as to present its flat surface h beneath the punch, andsaid plate is provided with a hole 7t, which receives the end of atrip-lever l, pivoted in the neck I) and having its upper end 1projected into the slot in the rear portion of the cam m of thepunch-lever n. This punch-lever is pivoted between ears 0 of the head 0by means of the pin 19, entering the slot g, and. a stoppin r is used tolimit the forward and backward throw of the said punch-lever. Adjacentto the slot in the cam m is a cam-surface s, which cooperates With thetrip-lever Z when the punch-lever is thrown forward to upset the eyeletor rivet in order to positively move the sliding-plate inclinefforwardto present its surface 1' beneath the punch and permit the punch torecede under the action of the plunger 15.

Any tendency of the sliding plate to stick and refuse to return underthe action of the spring when once moved forward is overcome by thepositive movement of the trip-lever Z, effected by the engagementtherewith of the shoulder s of the punch-lever when the punch-lever isthrown over backward, or to the left, Figs. 1 and 2, which movement ofthe trip-lever starts the return of the sliding plate and again rendersthe spring j effective. Thus one difficulty sometimes occurring in thepresent type of presses is overcome.

The form of plunger herein shown and preferred for use in this presscomprisesa plunger'tube if, supported bya spring 2?, arranged within thehead c, the said tube t being adapted to receive a secondary plunger u,which is supported by a spring a, which spring normally tends to'retainthe secondary plunger within the said tube 25. In the act of perforatingthe fabric and inserting the eyelet or rivet the secondary plunger umeets the stationary punch e and recedes within the slotted portion ofthe cam. of the punch-lever; but in the act of upsetting or clenchingthe eyelet or rivet the solid portion of the cam comesintoalinement withthe secondary plunger, and thus the plunger as a whole opposes a solidface against the eyelet or rivet to be upset.

I do not limit my invention to the use of a ICU hole such as shown inplatefto effect ongagement of the plate with the trip-lever, althoughthat construction probably is as simple, cheap, and effective as any.Various substitutes for this connection may be used so long as they arecapable of effecting the desired operation.

What I claim is 1. An eyeletpress, having a plunger, a punch-leverprovided with a shoulder, a punch, and a spring-pulled sliding-plateincline, combined with a trip-lever engaginga hole in the saidsliding-plate incline and adapted to be engaged by the shoulder of thepunch-lever to forcibly retract the sliding plate, substantially asdescribed.

2. In an eyelet-press, a sliding-plate incline, having a hole inone end,a spring for normally drawing the said incline in one direction, and atrip-lever engaging the said hole, combined with a punch, aplunger, anda punch-lever having a cam-surface and a shoulder cooperating with thetrip-lever, substantially as and for the purpose described.

3. An eyelet-press, comprising a slidingplate incline, a spring fornormally drawing the said incline beneath the punch, a tripleverengaging a hole in said incline, a punchlever having a slot, a shoulder,and an internal cam-surface with which said trip-lever cooperates, and aplunger, substantially as described.

4. In an eyelet-press of the class described,-
